Within every cell (except red blood cells) is a nucleus -- a sphere-like structure separated from the rest of the cell by a membrane. The nucleus acts as the cell's control center, regulating its ...

Red blood cells are disc-shaped cells with no nucleus. They are very small but their flattened shape gives a relatively large surface area which allows rapid diffusion of oxygen.

Researchers at the Department of Biomedicine at Aarhus University are the first in the world to uncover the precise structure ...

CD163 might not be the most exciting name in the world, but behind it lies one of the body's most important defense receptors ...

CD163 is a macrophage receptor that clears hemoglobin-haptoglobin complexes from blood, preventing oxidative damage and also ...

Since red blood cells contain large amounts of hemoglobin ... normal hemoglobin had a glutamic acid residue 3. The atomic structure of hemoglobin, determined by Max Perutz and colleagues 4 ...

Molecules of sickle-cell hemoglobin stick to one another, forming rigid rods. These rods cause a person's red blood cells to take on a deformed, sickle-like shape, thus giving the disease its name.

Researchers have identified how haptoglobin and CD163 protect the body from oxidative damage from free hemoglobin by ...
